Pros
- Cordless design eliminates hose tangles and simplifies storage
- Long battery life covers large in-ground pools without frequent recharging
- APP control adds convenience and customization for daily or periodic cleaning
- Effective wall-climbing and waterline cleaning reduce manual scrubbing
- Dual filtration system keeps pool water clean and clear
Cons
- No customer reviews yet, so long-term reliability is unverified
- APP must be set before placing the cleaner in water, limiting on-the-fly adjustments
- Dimensions (15.9 x 15.7 x 11 inches) may be bulky for smaller pools or tight storage spaces
The Letexpool C1 is a cordless robotic pool cleaner designed for in-ground pools up to 1615 square feet. It targets homeowners who want a hands-free cleaning solution without the hassle of hoses or cords. With wall-climbing ability and seven cleaning modes, this robot aims to handle floors, walls, and waterlines automatically.
Standout features include triple motors and dual rolling brushes that provide strong suction and scrubbing power. The dual-layer filtration system traps fine dirt, leaves, and sediment, keeping water crystal clear. In real-world use, the 180-minute battery life covers large pools in a single charge, and the fast 2.5-hour charging minimizes downtime. The smart APP control allows you to switch modes and customize paths, though you must set it before the robot enters the water.
Build quality appears solid with a rugged Obsidian finish. The cordless design eliminates cord tangling and makes storage easy. However, at 15.9 x 15.7 x 11 inches, the unit is relatively large, so it may not fit in tight spaces. The lack of user reviews means we cannot confirm long-term durability, but the feature set suggests good value for the price.
A potential drawback is the app requirement: you cannot change settings while the robot is submerged, which may be inconvenient if you want to adjust mid-cycle. Additionally, the product is new, so customer support and firmware updates are unproven. For most users, the convenience of cordless operation and wall-climbing will outweigh these minor concerns.
Overall, the Letexpool C1 is a compelling choice for pool owners seeking an automated, cord-free cleaning experience. Its combination of long battery life, multiple modes, and APP control makes daily pool maintenance much easier. If you have a large in-ground pool and want to reduce manual work, this robot is worth considering.
Buying Guide: What to Consider for Your Saltwater Pool
1. Salt Cell Protection and Descaling
Saltwater pools rely on a salt chlorine generator (SWG) cell to produce chlorine. Over time, calcium and mineral scale can coat the cell plates, reducing efficiency and lifespan. A dedicated salt cell cleaner, like the PoolFix Salt Cell Cleaner or the AquaDoc Salt Cell Cleaner for Saltwater Pools, helps dissolve these deposits without harsh acids. Regular cleaning every 60 to 90 days maintains optimal output and avoids costly replacements.
For a comprehensive approach, consider robotic pool cleaners with advanced filtration. For more on obstacle avoidance features, see our article on best large pool cleaner with obstacle avoidance.
2. Algae Defense and Water Clarification
Saltwater pools are not immune to algae. In fact, warm temperatures and sun exposure can encourage blooms. An algaecide like the Clorox® Pool&Spa™ Swimming Pool Algaecide or the HTH 67244, Swimming Pool Care Algae Guard provides long-lasting protection. These non-foaming formulas work well with saltwater systems. For persistent issues, a mineral unit like the PoolRX+ pool unit 7.5k-20k gallons reduces chemical demand and controls algae for up to six months.
Combine these with regular filter cleaning. The HTH 67227, Swimming Pool Care Filter Cleaner, 32oz improves filtration efficiency, keeping water clear. For above-ground pool options, explore best above ground robotic pool cleaner overall.
3. Robotic Cleaner Performance and Convenience
For large in-ground saltwater pools, a robotic cleaner saves time and effort. The [2026 NEW] C1 Robotic Pool Cleaner with 180Mins features wall-climbing ability, dual filtration, and smart app control. Its long battery life covers large pools without frequent recharging.
